  • Design Pattern Automation

    Despite the high total cost of ownership of a line of code, a lot of boilerplate code still gets written every day. Much of it could be avoided if we only had smarter compilers. Indeed, most boilerplate code stems from repetitive implementation of design patterns that are so well-understood that they could be implemented automatically if we had a way to teach it to compilers.

  • Faster, Better, Higher – But How?

    One of the main challenges when designing software architecture is the consideration of quality attributes. Not only their design turns out to be difficult, but also the specification of these attributes. Consequently, many problems in software systems are directly related to the specification and design of quality attributes such as modifiability or performance, to name just a few.

    While the principal pattern is easy to understand it can be difficult to succeed with Dependency Injection without considering the larger context. DI is an application of the principle of Inversion of Control and to succeed with IoC you’ll also need to invert your thinking. This article provides a sketch of the mental model you need to adopt to succeed with DI.
